Let me demonstrate you这句语法错误了吗？

demonstrate 是一个可以跟双宾语的动词，也就是说它的用法类似give，即demonstrate ** sth 或变形为demonstrate sth to **。由此看来，原句缺少直接宾语，因而出现语法错误。

纠正：Let me demonstrate it to you.

及物动词用法？

及物动词的主要用法。及物动词后面必须跟宾语。可以用于："主+谓+宾"；"主+谓+双宾"；"主+谓+宾+宾补"结构。如：He reached Paris the day before yesterday.Please hand me the book over there.They asked me to go fishing with them.类似的还有：buy,catch,invent,get,found,like,observe,offer,prevent,promise,raise,find,forget,receive,regard,see,say,seat,supply,select,suppose,show,make,take,tell....作不及物的动词。不及物动词后面不跟宾语。只能用于："主+谓"结构。This is the room where I once lived.类似的还有：agree,go,work,listen,look,come,die,belong,fall,exist,rise,arrive,sit,sail,hurry,fail,succeed....两用且意义不同的动词如begin 都是作"开始"讲。everybody,our game begins. let us begin our game. 类似的还有：start,answer,sing,close,consider,insist,read,learn,prepare,pay,hurt,improve....这类动词作不及物动词是一个意义；而作及物动词时却是另一个意义。如lift作不及物动词时是指烟雾的"消散"。we saw the mountain when the clouds lifted. 作及物动词时是"升高；举起"。He lifted his glass and drank.类似的还有：beat　vi.跳动 vt. 敲，揍，打；　grow vi.生长 vt.　种植play vi.玩耍 vt. 打（牌、球），演奏 **ell vi.发出（气味） vt. 嗅ring　vi.（**、铃）响vt.打**　speak vi.讲话　vt. 说（语言）hang　vi. 悬挂 vt.　绞死　operate vi.动手术　vt. 操作在英语错误中，“及物动词+介词+宾语”（transitive verb+preposition+object），是常见的一种。所谓及物动词，就是谓语动词（predicative verb），不必通过介词引荐宾语。相反的，不及物动词（intransitive verb）是不带宾语的。有许多动词，虽然性质是及物的，但不一定要有宾语，如下列的①a和②a便是这种情形：①a. We study every day.b. Do you study English every day?②a. Please write clearly next time.b. Can you write your composition now?如果本质上就是不及物动词，就不会有宾语；若要宾语，就要借介词之助，一起连用才行（不及物动词+介词+宾语），如③b和④b；③a和④a是错的；*③a. The children are listening the music.b. The children are listening to the music.*④a. She is laughing the crippled man.b. She is laughing at the crippled man.反之，及物动词不必靠介词，就可以带宾语，如上述的①b和②b ，又如⑤和⑥：⑤ John is giving a book to me.⑥ Who will answer this question?如果无意中把介词加上，就错了，如：*⑦ Who will answer to this question?下列这句从房地产广告中看到的句子，也犯了同样的错：“We have many buyers awaiting for available units here.”“awaiting”是个及物动词，后面的介词“for”是多余的，要去掉；不然把“awaiting”改为“waiting”也行。许多人习惯上喜欢把介词加到及物动词后面，然后才带出宾语。最常见的是“emphasize/stress on/upon”和“discuss about”，如：⑧ Singaporeans seem to have emphasized on material gains.⑨ In our education system,we stress upon examination results.⑩ World leaders spent a lot of time discussing about worsening economic problems.显然的，这三句里的介词“on/upon”和“about”是多余的，不必要的。

demonstrated that后面用有主语吗

看是哪一种情况吧：

1 It 作形式主语，后面加一个完整的句子，需要主语：It is demonstrated that light travels faster than sound. 这时demonstrated是过去分词，表示被动关系，整个句子相当于一个主语从句的变形：That light travels faster than sound is demonstrated.

2 人或物作为主语，that后面解一个完整的句子，这个句子中有主语，而整个句子是一个宾语从句。此时，demonstrated是动词的过去式，表示动作发生在过去。

例如：The experiment demonstrated that defects exist in this crystal.

3 that指代一个句子，通常是某个观点，这个句子在demonstrate前面出现了，使用that只是为了使得整体变简洁些。这样that后面可以加一下状语。例如: The theory was an ideal one and Jim demonstrated that by carrying out a XRD experiment.

能想到的就这些，希望对你有帮助。
